The mold needs draft and draw, the angles of the part must allow it to release. I have the equipment to bag parts, it is not always necessary, the thing it does do is remove the excess resin and thus reduce the weight without reducing strength. Another factor on composites, 100% of the load/stresses goes through the stiffest fiber (carbon) until it fails, then it transfers the load to the glass if you are using a multi fiber composite structure..... The grain direction of a unidirectional is critical, 4* off of the direction of the grain can lose up to 99% of the stiffness in that direction . Tim
That 4Deg comment is surprising, and why bother with fiberglass when using CF, unless its Kevlar or nomex? i also would make sure everyone understands the resin/glue adds almost no strength to the the item, mainly adds weight, its all about the fiber, but it must be held in place by the resin.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
